An assembled battery has improved reliability by facilitating and strengthening adhesive fixation of battery cells to a holder and a case and by accurately positioning electrode terminals. The assembled battery includes a battery cell (150) having a cap surface (151) and an opposing can bottom (155), a holder (120) holding the battery cell (150), a case (110) that engages with the holder (120) and houses the battery cell (150) together with the holder (120), a first adhesive portion (170) adhering the battery cell (150) to the holder (120), and a second adhesive portion (180) adhering the battery cell (150) to the case (110). The first adhesive portion (170) is provided between edges of the cap surface (151) and corresponding portions of the holder (120), and the second adhesive portion (180) is provided between a substantially central portion of the can bottom (155) and a corresponding portion of the case (110).
